Hi,
my question is related to a multi-variable control system (in fact it is a two-variable control system). There are two input variables into the system and two output variables which I want to control by using controllers for the input variables. The system is non-linear and can not be modeled mathematically. The greatest issue is that both input variables influence both output variables.
I’ve done some tests for a feedback control system regarding the first input variable and the first output variable. I’ve put in a PID controller and I’ve tuned the controller parameters using the Ziegler-Nichols methods. The system works really fine in this case.
Does anyone have an idea how I could switch now from the Single-Input-Single-Ouput system to the Multiple-Input-Multiple-Output system?
Thanks a lot!
